14.Which of the following is a property of the sampling distribution of ? (A)if you increase your sample size, will always get closer to μ, the population mean. (B)the standard deviation of the sample mean is the same as the standard deviation from the original population σ. (C)the mean of the sampling distribution of is μ, the population mean. (D) always has a Normal distribution. (E)If the population is not normal, the Central Limit Theorem is invalid.

5.What is meant by the term "90% confident" when constructing a confidence interval for a mean? (A)If we took repeated samples, approximately 90% of the samples would produce the same confidence interval. (B)If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the sample mean. (C)If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the true value of the population mean. (D)If we took repeated samples, the sample mean would equal the population mean in approximately 90% of the samples. (E)We are 90% confident that 90% of the data falls within the confidence interval.
